Abstract

The embodiment of the invention provides a power grid defect detection method and system, and the method comprises the steps: obtaining a feature map corresponding to a to-be-detected power grid inspection image, the feature map comprises a plurality of grid points, and each grid point corresponds to one region of the image; grid points in the feature map are divided into a first class and a second class, the first class represents a defect area, and the second class represents a background area; merging the grid points of the first type to obtain a connected domain; and inputting the connected domain into a pre-trained target detection network to obtain a defect detection result output by the network. According to the embodiment of the invention, the proportion of the defect target in the whole picture is very low for the power grid inspection picture which is data with a complex background, and the accuracy of the model can be obviously improved by extracting the target and then performing classification regression on the target through a coarse-to-fine rapid power grid defect detection method.
